More LS2 info
LS2 heads are the same as those on an '01 (375hp) LS6. Note that they use the shorter, solid-stem valves rather than '02-'04 (405hp) LS6's exotic, longer, hollow-stem intake valve and sodium-potassium("NaK")-filled, hollow-stem exhaust valve. Because the LS2 camshaft is less aggressive, lighter valves are unnecessary to keep the valve train stable all the way to LS2's 6600-rpm rev limiter. The rest of the LS2 valve gear is also the same as '01 LS6.
The cam in the LS2 is similar to the '01 LS6 cam. It uses the same profile but the part number is new because the cam position sensor target was moved from the cam to the camshaft sprocket. Valve lift is .525-in. and duration at .050-in lift is 204o int/211o exh.

Heads are revised Ls6 heads, so they are good to go.
Don't know if the crank is 100% interchangeable.
